It is necessary to connect an AC neutral wire to the “AC Neutral” bus bar
within the PSX-240-Relay. The torque for the screws in the neutral bus
bar varies depending on the hole in which the wiring is installed. The
larger of the two hole sizes in the neutral bar are the MAIN HOLES; the
smaller holes are the TAP HOLES. The wire size range and torque specs
are shown in the table below. Lower torque may be required when
utilizing stranded wire.
Main Holes Tap Holes
1/0-14 AWG: 50 in-lbs 6-14 AWG: 40 in-lbs
It is also necessary to connect an AC Hot L1 wire originating at the
system’s “AC Hot Out L1” bus to the left most breaker (assuming the
breakers are positioned on the right side of the enclosure) and an AC Hot
L2 wire originating at the system’s “AC Hot Out L2” bus to the right
most breaker within the PSX-240 Relay.
25A Breakers
10-14 AWG: 20 in-lbs
A ground lug is positioned near the breakers within the PSX-240-Relay.
The ground wire making connection to this ground lug should be the
same gauge as the neutral wire entering the PSX-240-Relay.
Ground Lug
2-14 AWG: 40 in-lbs
The PSX-240-Relay comes with three feet of 16 AWG SOOW, two-
conductor control wiring. This control wiring connects to the Auxiliary
+ (AUX+) and Auxiliary – (AUX-) terminals of one of the FXs in the
system. To locate these terminals, refer to the FX manual. The polarity
of the auxiliary output connections does not matter, they will work either
way.
There is some required MATE programming for proper operation of the
PSX-240-Relay. This information can be found in the next section of
this manual.

Programming Instructions
The following FX programming is necessary to use the auto-disconnect
feature of the PSX-240-Relay. Before programming, turn off the AC
input breakers. Also make sure that the control wires from the PSX-240-
Relay are connected correctly to the Auxiliary + (AUX+) and Auxiliary –
(AUX-) terminals of the FX that you intend to control the PSX-240-
Relay.
Here are the programming steps (MATE screens shown on following
page):
• From the MATE’s “Main” screen, press the soft key,
key in the password, and then press the soft key.
• Press the and soft keys on the next two screens
respectively.
• Press the soft key on the ADV/FX/PAGE3 screen.
• If the FX intended to control the PSX-240-Relay is connected to
a HUB, press the soft key repeatedly until its port
designation appears in the upper right corner of the screen.
• On the “Aux Output Control” screen adjust the value to “Auto”
by using the and > soft keys.
• Press the > soft key to get to the ADV/FX/AUX “Aux
Output Function” screen.
• Adjust the value on this screen to “AC Drop” by using the
and soft keys.
• Press < DOWN> repeatedly until you reach the “End of
Auxiliary Menu” screen.
• Press the soft key to return to the “Aux Output Control”
screen.
• Someone needs to be very close to the PSX-240-Relay to listen
for a click ensuring the FX is correctly programmed and the
PSX-240-Relay works properly. Press the soft key and
listen for the relay in the PSX-240-Relay to click. Once you
hear the click, press the <DEC> soft key to return the value to
“AUTO”.
